Can I compare the British and Danish prices directly?

Not as like for like. Great Britain’s figure is an imbalance price, Denmark’s is a day-ahead auction price and Australia’s is a real-time dispatch price; each answers a different question.

Why do the U.S. rows show only demand?

The board publishes a price only from a source whose licence allows republication. For the U.S. grids it shows EIA-930 demand, which is public data.

What does a dash mean?

The market does not publish that figure, or not in a form we may republish. It is not a zero.

Why do the rows show different times?

Each source publishes on its own schedule: every five minutes in Australia, every half hour in Great Britain, hourly with a delay in the U.S. Every row shows its own as-of time.

What happened on 13 November

Prices fell below zero in 3 markets on 13 November: South Australia for 1 h 10 minD, Queensland for 30 minD and Victoria for 5 minD. The longest unbroken run was in South Australia, 35 minD from 09:55–10:30 ACDT; the lowest price there during the day was −A$21.01D/MWh. The run sat inside local daytime hours, when rooftop and utility solar in the NEM is producing. This site does not publish a generation mix for the NEM regions, so the solar and wind share in those intervals is not shown. Great Britain spiked to £273/MWhD (about 361D USD/MWh) in the hour from 17:00 GMT, above our fixed threshold of 300 USD/MWh.

The highest renewable share among the metered grids was in Denmark: 83.9D % across the day, with wind at 79.3D % and solar at 4.6D %. Great Britain followed at 41.7D % renewable with wind 30.0D % (transmission-metered; solar on local networks is not in this data). Taiwan followed at 9.3D % renewable with wind 0.5D % and solar 7.4D %. The 8D markets with complete demand data used 2,041,661D MWh between them, led by Taiwan with 34.7D %.

Time below zero across all markets added up to 1 h 45 minD, less than the 7 h 25 minD on 12 November. Queensland went below zero after staying positive the day before. Tasmania stayed above zero this time. Electricity used rose most in Victoria (+9.2D %) and fell most in Great Britain (−5.3D %). Denmark's renewable share rose by 4.4D points, from 79.5D %. Great Britain's renewable share fell by 9.7D points, from 51.4D %. Taiwan's renewable share fell by 2.6D points, from 11.9D %. The cheapest hour anywhere cost about −4D USD/MWh, against −6D on 12 November.

How to read this. The 13 November recap covers 15D markets (8D with a full day of demand) and was frozen at 00:30 UTC on 14 November; later operator revisions are not applied. A D badge marks a number we calculated from the operators' metered data, an M badge one published as is. Durations add up priced intervals below zero, clock times are each market's local time, and shares are energy-weighted over the day. Definitions and limits are in the methodology.

ⓘ How this recap is made

Built once after the UTC day ended, then frozen. Electricity used is the metered demand of each market added up over the day (Great Britain: transmission generation); only markets with at least 95 % metered coverage of the day are added up. Hours are UTC hours priced as the mean of the source periods. Below zero is the sum of priced intervals under zero. Nothing is estimated or filled in.
